【OpenGL】鼠标控制三维物体移动（添加光照、材质）

图形学期末作业
软件用的vc++6.0 鼠标控制小茶壶移动，桌子可以改成点绘制贴图。

// 设置观察视野为窗口大小（用FLASH里面的话来说应该叫设置摄象机视野）

/鼠标点击

void MousePlot(GLint button,GLint action,GLint xMouse,GLint yMouse){

if(button==GLUT_LEFT_BUTTON && action==GLUT_DOWN){
	mouseDx = xMouse;
    mouseDy = yMouse;

}

    if(button==GLUT_LEFT_BUTTON && action==GLUT_UP){
    glutPostRedisplay();
}
}
鼠标移动

void MouseMove(GLint xMouse,GLint yMouse){
//angle+=2;
	if(xMouse>mouseDx && yMouse==mouseDy)
		{rx=0;ry=1;}
	else if(xMouse<mouseDx && yMouse==mouseDy)
		{rx=0;ry=-1;}
	else if(xMouse==mouseDx && yMouse<mouseDy)
		{rx=-1;ry=0;}
	else if(xMouse==mouseDx && yMouse>mouseDy)
		{rx=1;ry=0;}
	else if(xMouse>mouseDx && yMouse<mouseDy)
		{rx=-1;ry=1;} 
	else if(xMouse>mouseDx && yMouse>mouseDy)
		{rx=1;ry=1;}
	else if(xMouse<mouseDx && yMouse<mouseDy)
		{rx=-1;ry=-1;}
	else if(xMouse<mouseDx && yMouse>mouseDy)
		{rx=1;ry=-1;}

	mouseDx = xMouse;
	mouseDy = yMouse;

	glutPostRedisplay();

}

 

// 主函数

int main(int argc, char* argv[])

{

	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
	glutInitWindowSize(600, 600);
	glutInitWindowPosition(300,160);
	glutCreateWindow("table");
	glutDisplayFunc(Display);
	 //glutPassiveMotionFunc(PassiveMouseMove);
	glutMotionFunc(MouseMove);
	glutMouseFunc(MousePlot);
	glutReshapeFunc(ChangeSize);
	init();
	glutMainLoop();

return 0;

}

效果：
